BEIJING - China has urged the international community to beef up anti-terrorism cooperation as US President Barack Obama called the recent shooting rampage in southern California "an act of terrorism."

China condemns the shooters in the incident and expresses condolences to the victims and their families, Foreign Ministry spokeswoman Hua Chunying told a regular press briefing.

Calling terrorism a common enemy of mankind, Hua said China is opposed to terrorism in any form, and calls for stronger global anti-terrorism cooperation.

Two gunmen shot down 14 people on Wednesday at a southern California social services center and injured several others. According to local police, "some degree of planning" was involved in the shooting spree.

During a Sunday night address, Obama said the two shooters were "self-radicalized," as no evidence had been found of links between the couple and any terrorist groups.
